A$500 television is on sale for 20% off. however, you must pay 6% in sales tax. what is the final price of the television after the discount and the tax? ( label your answer)

20% off means you are paying 80% of the original price ( 100% - 20% = 80%)

Multiply the price of the tv by 80% to find the sale price:

500 x 0.80 = 400

Now multiply the sales price by 1 plus the tax rate to find final cost:

400 x 1.06 = 424

Final price including tax is $424

A(√2) would be the correct answer.
